Oppenheimer Holdings Inc
A full-service investment bank and brokerage that advises wealthy families and businesses, offering wealth management, trading, and investment banking. Its roots trace to Fahnestock & Co., founded at Two Wall Street in 1881, yet it carries the name of Max Oppenheimer, a Jewish refugee from Nazi Germany who launched Oppenheimer & Co. in 1950. When Fahnestock bought the Oppenheimer brand's U.S. operations in 2003, it renamed itself after that storied name.
